WILLIAM H. MOAULEY, OF NEW YORK, N. Y.

CLAMP.

SPECIIEICATION'Y forming part'of Letters Patent No. 302,346, dated July 22, 1884. Application [iled December 1l, 1853. (No model.)

Be it known that I, WILLIAM H. MCAULEY, of New York city, in the State of New York, have invented certain new and useful Improvementsrelating to Clamps and I do hereby declare that the following is a full and exact description thereof. l

The invention may be used for various purposes; but it is moreparticularly intended for pressing moldings intoy place in'the angles between the panels and the stiles of doors, shutters, and analogous paneled constructions, and

Vholding them there,if necessary,u1`1til the glue l this specification. Figure lis a side elevation representing the device applied to the edge of a door, the latter being shown in cross-section. Fig. 2 is a section through 'the clamp and jaw and its guiding-brackets on the line a' x in Fig. l. Fig. 3 is a plan view of av portion of the mainbottom piece of the clamp. Fig. 4 is a section through the screw at and near the foot. Fig. 5 is an end View of the screw.

Similar letters of reference indicate corre sponding parts in all the gures where they occur.

A is the base-piece, and B brackets, of wrought-iron or other suitable material, in the form of a strap, encircling A, and secured by screws b. A is a plate of iron' or steel, secured upon the upper surface of A, and pre-l senting'a series of points, a, on its upper surface.

` C is a clamping-piece iitted to traverse between the brackets B, and be guided thereby. It is operated by a cylindrical rod, C', rigidly attached and extending through a hole in A. A considerable length of the rod C is screwthreaded, and receives a thumb-nut, D, by turning which the clamping-piece C can be brought forcibly down toward A, clamping` the stile M of the door between the parallel surfaces presented. y

E is a pivotv connecting the upperY ends of A the brackets B, and serving as a fulcrum for a lever, G, through which is tapped along screw, I'I, which m'ay be of wood, having a concave shoe, Il', of iron or steel, adapted to engage on-one of the points a, and allow the shoe to be operated forcibly without danger of the foot slipping.

In using the invention,the screw His slackened, and the clamp applied upon any desired portion of the edge of the door by turning the thumb-nut D. The surfaces of the molding P which are to apply against the stile M and against the fillet N are properly coated with glue and applied in the required postion,and, planting the foot of the screw H on the most convenient point a, the screw is forcibly turned, causing the clamp-lever Gto exert a pressure with its rounded bearing-surface G against the molding I?. The force is applied in the directionindicated by the arrow, so that it not only holds the molding I in firm contact with the llet N, but also in such contact with the perpendicular adjacent surface of the stile M.

A number of my clamps may be applied close together to exert a great force on the molding. In most cases it will suffice to have a few of the clamps distributed evenly along theedge of the door to be treated. It will be understood that a similar or a different molding will ultimately be applied on the opposite side of the panel to iit in the angle lbetween the fillet i and the stile on that side. Under ordinary conditions the panel O will be left unglued, and will be freeto expand and contract, as

yusual,while it is held reliably in place by the vantages of the invention.` I can make cavities in the plate A', instead of raising projections a thereon; but such cavities are liable to be lled with sawdust, glue, and the like. I much prefer the projections or spurs a, adapted severally to engage in the hollow in the foot of the screw. The block which presents the rounded bearing-surface G may be attached either permanently or temporarily to the lever G, if desired; but for most cases it may be inserted as a separate block.

I claim as my invention- 1. In combination with the base A, having engaging means, a, the frame B, secured to such base, and the movable clamp C, a lever, as G, pivoted to the frame B,and a screw, H, operating through said lever and against a portion of the base to give a clamping-pressure to said lever in a direction oblique to the plane of the main clamp, asset forth.

2. The combination of the base A, having WM. H. MOAULEY.4 [L s] Witnesses:
